To prmuntc the rluxtirity of tln: foot und tu rnnllle this (wallet-tion of lumcs thus urticulnttul (ur Joined) to mpi-rlp' support. the wright of tha lnnly, tin-.y nrc arranged iu ,the funn nf arches nl' domes.

Thum nrt-lues nrc held tngether' by ligxt ments and Inusrles und lun tendons nf the nnmrles in the cnlf of the lEg. ["rve nrtio'n u? pmrurml {nnl in plan-u of the fmt being l'lgul m uctxun, xt is springy nud highly elnstlc.

.The longitudinal art-h, the most impot tum nnc,.extrndin v from the heel fox-wurd tn til-st metutn'rm -plmhmgenl joint,` takes in the tnrsn-I und mrtntnrsnl bones from the inner side. It is this urrh where flut 'font dcrvlops. The nnt'rior lurtntxirsul arch extrnding rrnsnriso of tlw fcmt hotu'crn the lil-xt nud 'fifth mctulursul (freut und littlvl tw) is' formed by thr hun: s uf the metatursul lusnvs.' Wlwlrtlwul imucs drop grunt puin und trnulrlc is noted. Thru uf less itupnrtunvr is thu nnlvr luugritudiuul m'rh und thu trnusirrsr nrrh ut tho hcols of tho nwhr tnrsnls nud tho thrrv runrifnrlu und rulmid llmws.

'flw strut-turc of the font from :l mechanirul paint of view is pvrfrt'od. :is enrh time tln` wright nf tllr lmdy is thrnwn .suddrnly un tho t'mvt. tlusupporting mum'lvs und li u- Figs. 1 und 2, it will be leen that the heel section of the in te is extended upwardly and around the eel of the foot as ut 3. This forms n natural recess or support for the os calci: or heel and coiperetes with the other arches formed in the plate, to prevent too much ilexinl or `rieldinl; of the-arches, particularly the ongltndina arch. The ex tenaion rovided by fonnin the plate to nclose tire lower part of the neel of the font forms n vperfect. support for same, which relieves the os celcis to a certain extent of too much pressure. It also at the sume time, forms e socket or receso for the heel, which holds it in a ri 'd position, in this manner preventrp,v sli 1n movement of the heel when weight is leed on the foot and' tbe longitudinal l yields. The distance between the os caltis indicated at 4x and the metatnml and phnlangenl articulations chown at is thus kept constant, in this manner supper-tin the nstragalus or middle cuneiform bones rom settling or cans-in r a llxt foot, heretofore described. 'lhe pY utc bein fo Vfrom e plaster rust of tbe foot fits zxact eurvatores of the awhesmnd es spreading of the lo itnglinnluurh isgprevented by reason of he wntruction fprovided, it will be seen that the other arrhes will he retained in position and perfectly luppoted In other words. the foot proper is prevented from sprmnling ont over tho plete or the -auilibrmm disturbed by dinplacement 'it be su portinv points. Thel plate has a mnmvse y lint orwurd bottom portion (Fig. 1) w'ltvh nuits upon the inmolol of the shoe and holds .he pluto firmly in' pa:-

imlooth und comfortable a surface as ossble but the materials and linieh muy eru'ise be such ns the judgment and experi ence of tbe manufacturer muy dictate.

l wish it nndewtmul that various changes in form, pmportions und minor details of 'construction may be resorted to within the scope of the nppended claim, and tbnt I do lot wish to limit myself to tbe specific desili und wnstrurtion -bere shown.

aving thus dcwrlml my invention, what I claim und desire to secure Patent i5- A A insel and arch sup mrtrr cmuprsing u metal plate formed to t the nrclles of the foot, ha ving.' its rear end bent to form u boel socket for surrounding the lower aide and bock portions of the brel, und boring its forward rnd arranged to terminate beneath the nntntarxal and pllnlangu'l.articulations of thofoot und formed ilut transversely to provide a broad soatingut its ru'ard end to u'itlmtand-uny Interni webbing of the bool. ond which latter point of support is mmpamtively nnrrou'.
